- Column Version length is extended from 10 to 255 so it can store md5sum's lenght (32 characters) that is needed by data streams created during ebulk tool ingestions used in wendelin.
- New column Size is needed to speed up ebulk tool and can generally be useful for DMS, so that we can search/sort document by size.

File is a top-level module document, like PDF, Text Document etc, so it
should have its own security definition and should not acquire local roles.

For cases where files are embedded as sub documents, we are using Embedded
File, which acquire local roles.

In "Attach document" action of erp5_ingestion, the default publication section of attach document suggested in the dialog is defined by a type based script.

We could do the same for group, so that we have a script that is easier to customize for specific cases. One use case is for accounting transactions, the group is usually the group of the entity where the document is attached.

Also, we could enable type based script in document scanner dialog, which is very similar to attach document dialog, but it was not using the scripts.

Similarly, we introduce a script to suggest a title in document scanner.

Another difference between "Attach Document" and "Scan Document" is that the later had a "publication state" field, allowing user to choose a state for the created document. We extend this to "Attach Document" as well and introduce another customizable type based method to be able to configure a default value.

They are often used to achieve surprising styling

This customizable type based method is used in "Attach Document" and
"Scan Document" dialogs, to set a default value in the dialog for the
publication state field.

This code is not used and rely on pdftk that we don't have installed in
slapos

Do not remove relative url, as they are ofter use in img tag

This allow to see the content when being displayed as a web page content

details is not always the last child

Extend "Attach Document" to have the same feature as in "Scan Document"
so that user can directly choose the state when uploading a document.

This simplifies a bit document_scanner, which can reuse the code that is
now in Base_contribute

document_scanner: introduce a customizable type based script to suggest a title for scanned document

Unlike when we attach a document, where the title comes from the filename of the attached document,
when we scan document we don't have any filename. There's a default behaviour of using the current date, so that title is not empty, but in some cases we can define a script to suggest a better title, for exemple when scanning an invoice, we can suggest using supplier name and the invoice title.

ingestion's dialog uses some type based methods for customizability, use
same type based methods here.

The default group of documents attached to accounting transactions can be
taken from the group of sections

Base_viewNewFileDialog/your_publication_section allows to easily suggest
a default publication section to the user, but the "group" was not so
easily customizable, it was just getting from document or user.

Introduce the same mechanism as for publication section, a type based
script that can be defined for each portal type.

On documents, we have an "Export" action for OOoDocument_viewConvertDialog.
When erp5_ods_style is installed, "Export to Spreadsheet" is added as a global
action. Both these actions were translated as "Exporter" in french, which is
confusing and a bit incorrect.
Use a proper, different translation for "Export to Spreadsheet"
